A man from Texas buys a round of drinks for everyone in the bar as he
announces his wife has just produced "A typical Texas baby boy weighing
twenty pounds." Congratulations shower all around, and many exclamations
of 'wow!' are heard. Two weeks later he returns to the bar. The
bartender says, 'Say, you're the father of the typical Texas baby that
weighed twenty pounds at birth, aren't you? How much does the baby weigh
now?' The proud father answers, 'fifteen pounds.' The bartender is
puzzled. 'Why? What happened? He already weighed twenty pounds at
birth.' The Texas father takes a slow sip from his beer, wipes his lips
on his shirt sleeve, leans over to the bartender and proudly announces,
'Had him circumcised.'
